@ET/JUE 1i. 50S/UZ Z5, @LOM/55 om Patented Oct. 10, 1950 RAIL FASTENINGDEVICE Arthur R. Schulze, Youngstown, Ohio, assignor toCarnegie-Illinois Steel Corporation, a corporation of New Jersey fApplication September 9, 1949,A Serial No. 114,870

6 Claims. (Cl. 23S-349) This invention relates to a rail fasteningdevice and is a continuation-in-part of my copending application, SerialNo. 752,775, filed June 5, 1947.

The rail fastening device described in my copending application issatisfactory in most respects, but it is necessary to limit thethickness of the spring clip because of the amount of deflectionrequired to insert the clip through the inverted U-shaped member. Inorder to have minimum corrosion effect, it is desired to use a thickerbut narrower spring clip which will give minimum surface area inrelation to the cross section. Also, I have found that it is necessaryto make adjustments as the clip becomes worn and the only way in whichthis can be done in my previous application, is by the use of shims.

It is therefore an object of my invention to provide a rail fasteningdevice which can be adjusted to compensate for wear.

Another object is to provide such a device which will last for a longtime.

These and other objects will be more apparent after referring to thefollowing specification and attached drawings, in which:

Figure 1 is a top plan view of the device;

Figure 2 is a sectional View taken on the line II--II of Figure l;

Figure 3 is a view, similar to Figure 2, showing a slight modificationof my device;

Figure 4 is a top plan View of another embodiment of my device;

Figure 5 is a sectional View taken on the line V--V of Figure 4; and

Figure 6 is an enlarged View showing a, detail of Figure 5.

Referring more particularly to the drawings, the reference numeral 52indicates a standard tie plate which is mounted on the tie in the usualmanner and which is provided with the usual rail seating portion 54 forreceiving the flange 56 of a rail. An inverted U-shaped member 58 iswelded to the base plate 52 on each side of the rail between the seatportion 54 and the edge of the plate. The top inner surface of themember 5B is provided with a plurality of serrations 60 therein whichextend generally parallel to the length of the rail. A spring clip 62passes through the opening 64 in the U-shaped member 58 with one endbearing on the tie plate 52 and the other end bearing on the top surface66 of the rail base. The inner end of the clip B2 is bent upwardly at 68so that it may be driven into position until it abuts the rail web 10which limits its inward movement. A serrated wedge shaped locking key 12is provided in the opening 64 between the top 2 of the clip 62 and theserrations 5l). The bottom surface 74 of the key l2 is arranged in theopening $4 at a slightly steeper angle than the top surface 66 of therail base. The difference between the two angles may be termed adifieren-1 ber 58 and the other jaw face contacts the large end of theserrated key 72. The jaws of the tongs are then moved together to slipthe key l2 into position. When it is desired to closely control theamount of pressure applied to hold the spring clip 62 on the rail,hydraulically operated tongs may be used with the hydraulic pressurebeing varied as desired.

If desired, the locking key 12 and serrations 60 can be arranged so thatthe large end of the locking key will be adjacent the rail as shown inFigure 3. In this case the locking key can be forced into place by meansof a lever having one end bearing on the web 'l0 of the rail.

The device can be disassembled by placing a block on the top surface ofthe spring clip `62 and pressing down on it with `a pinch bar having itsinner end under the rail head.

Figures 4, 5 and 6 show another embodiment of my inventionin which aninverted U-shaped member is provided but the top of the opening 82 inthe U-shaped member, instead of being a constant slope, is provided withtwo different slopes. Substantially one-half of the under surface isarranged at a differential angle 84 with the top surface of the railbase. The spring clip 85 is shaped as shown with a substantiallyhorizontal portion 86 and sloping portion 88. The ends of the clips arebent upwardly at 90 and v92, respectively.

The clip 85 is installed by driving it into position with its surface 94being compressed in the manner described more fully in my copendingapplication. The inward movement of the clip is limited by contactingthe end 90 with the web of the rail. This device, like that of Figure 1,may be used in conjunction with a serrated wedge.

While several embodiments of my invention have been shown and describedit will be apparent that other adaptations and modifications may be madewithout departing from the scope of the following claims.

I claim:

1. A rail fastening device comprising a tie plate having a seat portionfor the base of the rail, a member secured to said tie plate at a pointintermediate the seat portion and the edge of the plate, said memberhaving an opening therethrough with the top surface thereof being spacedfrom the top of said tie plate, said top surface having a plurality ofserrations therein extending generally parallel to the length of therail, an elongated spring clip extending through said opening with oneend of said clip bearing against the top of the rail flange and theother end bearing against the top of the tie plate, and a serrated wedgeshaped locking key in said opening between said clip and said topsurface, the serrations in the locking key being shaped to fl into theiirst named serrations.

2. A rail fastening device according to claim 1 in which the bottomsurface of the locking key is -arranged at a steeper angle than the topsurface of the ange of the rail.

3. A rail fastening device according to claim 2 in which the distancebetween the top of the plate and the underside of the Wedge issubstantially greater than the thickness of the plate.

4. A rail fastening device comprising a tie plate having a seat portionfor the base of the rail, an inverted substantially U-shaped membersecured to said tie plate at a point intermediate the seat portion andthe edge of the plate, the underside of said U-shaped member having aplurality of serrations therein extending generally parallel yto thelength of the rail, an elongated spring clip extending through saidinverted U-shaped member with one end of said clip bearing against thetop of the rail flange and the other end bearing against the top of thetie plate, and a serrated wedge shaped locking key between said clip andthe underside of said U-shaped member, the serrations in the locking keybeing shaped to fit into the first named serrations.

5. A rail fastening device according to claim 4 in which the bottomsurface of the locking key is arranged at a steeper angle than the topsurface of the flange of the rail.

6. A rail fastening device according to claim 5 in which the distancebetween the top of the plate and the underside of the wedge issubstantially greater than the thickness of the plate.
